The forward end of shaft 28 projects from the arbor I5, as shown in Figs. 1 and 2, and upon this projecting end there is swiveled a short crank 3| of a diameter larger than the bore of arbor I5 but not larger than the outside diameter thereof. It will be obvious that the nut 26 may be turned by the operator from either end of the arbor, that is by grasping the socket wrench 29 at one end or by grasping the crank 3| at the other end when it is in the position illustrated in Fig. 1. The crank 3| will swing up into axial alignment with shaft 28 however when the operator grasps collar and pulls it toward the left in order to remove it from the arbor, the position of the parts during this latter procedure being indicated in Fig. 2.

From the foregoing the operation of the reel mounting herein disclosed will be obvious to those skilled in the art. When the wire upon a given reel is exhausted the operated grasps co1- lar 2U and pulls it 01T the arbor, crank 3| moving into the axial position. The reel I3 is then removed also and a new reel put in its place, after which collar 20 is put back on the arbor and moved toward the right until the balls 22 snap into the groove 2|. In order to accomplish this, it is necessary for the operator either to pull crank 3| forward longitudinally or to push socket wrench 29 forwardly with one hand while pushing the collar 20 rearwardly with the other hand. As soon as the balls 22 snap into position the new reel is set with precisely the same amount of spring pressure as was used upon the preceding reel, provided of course there is no material difference in the breadth or thickness of the reels. Whenever it becomes desirable to vary the tension upon the wire in the machine, this may be accomplished by turning nut 26 in either direction from either end of the arbor, as may be most convenient. The set screw I1, I8 working in slot I6 of course prevents rotation of the arbor when shaft 28 turns, but the set screw is easily removable should it be desired to remove the arbor for any reason.

Obviously, the present invention is not restricted to the particular embodiment thereof herein shown and described. Moreover it is not indispensable that all of the features of the invention be used conjointly; since they may be employed advantageously in various combinations and subcombinations.
